Martial weapons may have up to one modifier, while caster weapons and offhand weapons may have up to two modifiers. In addition to the modifiers listed here, blue weapons can also have the "Improved sale value" modifier, improving its merchant sale price, and the "highly salvageable" modifier, increasing salvage yields from that item.
Weapons will not come with more than one modifier for a particular property, even if the modifiers have different requirements. For example, you will not find a focus with both Armor +5 (while Health is over 50%) and Armor +10 (vs Giants), nor will you find a wand with both Energy +5 (while hexed) and Energy +15, Energy regeneration -1. The only exception to this rule are received physical damage modifiers on shields.

Weapons from collectors in high-level areas will have the maximum values for modifiers, making them the equivalent of dropped rare weapons. Note that some crafter, collector, and quest reward items can come with strange or otherwise unattainable modifiers, which are not listed here.

Available modifiers

All common modifiers are listed here, grouped by item type. The equivalent inscription, if it exists, is given in the table, otherwise it is noted as "n/a" (not available). If a modifier cannot be found on a certain rarity of item, it is likewise marked "n/a", otherwise the available range for that rarity is listed.

Energy -5 weapons are used by casters to "hide" energy. It is effective against energy denial in PvP and can also save energy when using energy-draining spells such as Rebirth.

Unconditional Damage +xx% weapons were previously created through the abuse of an exploit. Also, it is rumored that some weapons that dropped during the first few weeks of gameplay "lost" their negative modifier (such as -5 energy or -10 armor while attacking) and thus became unconditional.

Martial weapons with the halves skill recharge of spells (Chance: 10%) modifier are only available from Weaponsmiths in Nightfall.

Caster weapons

Blue and purplestaves and wands may have at most one modifier, and goldstaves and wands may have up to two modifiers. Inscribable wands can always take two modifiers (inscription and wrapping), while inscribable staves can always take three modifiers (inscriptions, head, and wrapping).

Halves Casting Time (HCT) and Halves Skill Recharge (HSR) modifiers from multiple equipped items (e.g. wand + focus/shield) stack multiplicatively. Two HCT 20% items result in a 32% chance to HCT (when one modifier "kicks in" but not the other giving 0.2*0.8 + 0.8*0.2 = 0.32), plus a 4% chance to Quarter Casting Time (when both modifiers "kick in" giving 0.2*0.2 = 0.04). Skill recharge reduction is capped at 50% from multiple sources, so two HSR 20% mods simply result in a 36% chance to HSR (if both modifiers kick in, you still only get halved skill recharge so chance to HSR = 32% + 4% = 36%).

Duration reduction modifiers have been found for all conditions except Burning and Cracked Armor. Equivalent inscriptions are only available on offhand items, not on weapons.

Shields and focus items

Blue and purpleshields and focus items may have at most one modifier, and goldshields and focus items may have at most two modifiers. Inscribable versions can always take two modifiers (inscription and handle for shields, inscription and core for foci).

Focus items will only have a +1 <attribute> modifier for caster attributes as listed below. Shields can have +1 <attribute> for caster attributes as well as Strength, Tactics, Command and Motivation (although these last four attributes are believed to only be available for the shield's own attribute).

Shields can have two "Received physical damage" modifiers with the following conditions: while in a stance, while enchanted, and while hexed. The two modifiers will stack if both conditions are met. A shield with "Received physical damage -x (Chance: 10-20%)" cannot have another "Received physical damage" modifier.
